Mounting arrangement for a vehicle body roof panel

ABSTRACT

A mounting arrangement for a vehicle body roof panel for closing a roof opening in a vehicle body. A pair of hinge assemblies pivotally support the roof panel on the body for movement between open and closed positions. Each hinge assembly includes a body mounted hinge member and a panel mounted hinge member which are locked to each other by a ball detent when the roof panel is in the closed position. When the roof panel is in the open position, each panel mounted hinge member is detachable from its respective body mounted hinge member and the roof panel is thus removable from the vehicle. A pair of latch assemblies include latch members pivotally supported on the roof panel for movement between latching positions and unlatching positions. When the latch members are in the latching positions, they are engageable with respective body mounted pins to retain the roof panel in the closed position. When the latch members are in the unlatching positions, the roof panel is free to move between the open and closed positions. The latch members are associated with respective sleeve detents movable between locking positions and unlocking positions. In the locking positions, the sleeve detents lock the latch members in the latching positions. A pair of release levers are pivotally supported on the roof panel and each is connected by a Bowden cable to each of the sleeve detents. Actuation of either of the release levers moves the sleeve detents to the unlocking positions. The latch members are also associated with respective pin detents located within the sleeve detents and movable between locking positions and unlocking positions. When the sleeve detents are in the unlocking positions and the pin detents are in the locking positions, the pin detents lock the latch members in the latching positions. A pair of solenoids are mounted on the roof panel and respectively connected to the pin detents to move the pin detents from the locking positions to the unlocking positions. The solenoids are responsive to actuation of either of the release levers and to the position of a transmission selector lever such that actuation of either of the release levers when the transmission selector lever is in a &#39;&#39;&#39;&#39;park&#39;&#39;&#39;&#39; position causes the solenoids to move the pin detents to the unlocking positions. When the sleeve detents and the pin detents are in the unlocking positions, the latch members are free to move to the unlatching positions and the roof panel is free to move between the open and closed positions.

A pair of hinge assemblies pivotally support the roof panel on the body for movement between open and closed positions. Each hinge assembly includes a body mounted hinge member and a panel mounted hinge member which are locked to each otherby a ball detent when the roof panel is in the closed position. When the roof panel is in the open position, each panel mounted hinge member is detachable from its respective body mounted hinge member and the roof panel is thus removable from the vehicle. A pair of latch assemblies include latch members pivotally supported on the roof panel for movement between latching positions and unlatching positions. When the latch members are in the latching positions, they are engageable with respective body mounted pins to retain the roof panel in the closed position. When the latch members are in the unlatching positions, the roof panel is free to move between the open and closed positions. The latch members are associated with respective sleeve detents movable between locking positions and unlocking positions. In the locking positions, the sleeve detents lock the latch members in the latching positions. A pair of release levers are pivotally supported on the roof panel and each is connected by a Bowden cable to each of the sleeve detents. Actuation of either of the release levers moves the sleeve detents to the unlocking positions. The latch members are also associated with respective pin detents located within the sleeve detents and movable between locking positions and unlocking positions. When the sleeve detents are in the unlocking positions and the pin detents are in the locking positions, the pin detents lock the latch members in the latching positions. A pair of solenoids are mounted on the roof panel and respectively connected to the pin detents to move the pin detents from the locking positions to the unlocking positions. The solenoids are responsive to actuation of either of the release levers and to the position of a transmission selector lever such that actuation of either of the release levers when the transmission selector lever is in a park position causes the solenoids to move the pin detents to the unlocking positions. When the sleeve detents and the pin detents are in the unlocking positions, the latch members are free to move to the unlatching positions and the roof panel is free to move between the open and closed positions.

SHEET E OF A ATTORNEY PATEHTED SEP 7 l9?! SHEET M UF d INV/g/V HRS ATTORNEY MOUNTlNG ARRANGEMENT ll fllt A VlEllilllCLlE llllUDY ROOF PANEL This invention relates to amounting arrangement for a vehicle body root'panel.

lt is well known for vehicles to include root" panel openings and roof panels for closing the openings to provide convertiblelike vehicles. Conventionally, these roof panels are removable from the vehicle or pivotally mounted for movement between open and closed positions. This invention provides a mounting arrangement for a roof panel wherein hinge assemblies support the roof panel on the body for movement between an open position in which the roof panel is removable from the vehicle and a closed position wherein latch assemblies and the hinge assemblies cooperate to retain the roof panel in closed position during operation of the vehicle.

One feature of this invention is that it provides a mounting arrangement for a vehicle body roof panel wherein hinge as semblies pivotally mount the roof panel on the body for move ment between a closed position and an open position in which the roof panel is removable from the vehicle. Another feature of this invention is that the hinge assemblies cooperate with latch assemblies to retain the roof panel in closed position during operation of the vehicle.

FIG. 1 tis an electrical circuit diagram.

Referring to l 'lG. l, a vehicle g ncrally indicated at 2.0 includes a windshield and a. windshield header 2d. Laterally spaced hinge assemblies pivotally mount a roof panel Jlti on a. rear roolportion Ml for movement between an open position, as shown, and a closed position, in which the roof panel flltr is engage-able with the windshield header M- as will be hereinafter described.

Referring to FEGS. Ml and ll, a. right-hancl hinge assembly Bill and a symmetrical left-hand hinge assembly, not shown, pivotally support the root panel 26:] on the rear roof portion The hinge assembly 3d includes a body mounted hinge member 32 conventionally secured to the roof portirm Ki l and a panel mounted hinge member nally secured to the roof panel The body rnourr l hinge member 32 has an aperture 3b which receives a bushing llt'l that supports a rod d0. One end of rod l0 receives first and second nuts and M. The nut 42 has an aperture lti that receives one end of a helical spring ll-ll, the other end ol which is received within an aperture fill in the body mounted hinge member Slit. The other end of rod dil includes annular lugs 52 and M integrally connected by n web fin. The by 52. and 5M support a hinge detent member which includes a slot oil that accepts the web 56. A setscrcw s2 retains web 556 in slot bl). The spring ltl biases the rod itl in a positive right-hand direction as viewed in H6. Ill or clockwise as viewed in FIG. it] to bias the hinge assembly Bill from the solid line closed position to the phantom line open position.

Referring to H68. 12 and 113, the hinge detent member 5? has a longitudinal bore M which slidably receives a pin 66 that is threadably mounted in the panel mounted hinge member The hinge detent member 5% also has a closed end bore 67 parallel to bore M- and receiving a plunger till that is spring biased outwardly of member 5! When the hinge assembly 31) moves to the closed position, plunger 655 abuts a conventional body mounted adjustable stop 7b, as in EEG. ill, and moves to a depressed position shown in H6. 12. When the hinge as sembly 30 moves to the open position, the plunger 68 moves to an extended position shown in FllG. 13. Movement of the plunger 68 controls a ball detent 72. that is carried within a detent bore 73 that connects bores fi l and 67. When the plunger 68 moves to the depressed position, the ball detent 72 moves to a position within bore 73 such that an annular groove '74 in the pin 66 receives the ball detent 72 and locks the panel mounted hinge member 345 to the hinge detent member and consequently to the body mounted hinge member 32.. When the plunger es moves to the extended position, an annular groove '76 in plunger 6% aligns with bore 73. If pin no is then withdrawn from bore 64, the ball detent 72 will move within bore 73 to a position within groove 76 in plunger (ill. Withdrawal of the pin (to is thus concomitant with the release of the panel mounted hinge member M- from the hinge detent member Ell and removal of the roof panel 2h from the vehicle Ml.

lt will be noted that a pin 78 mounted on the hinge detent member b'il cooperates with a groove lid in the plunger (i l to limit the movement of plunger as within bore 67. This prevents the plunger 63 from moving past the extended position shown in F116. l3 and possible loss thereof. l-linge detent member 53 has an annular rib ill that slightly reduces the diameter of bore '73 at the end thereof adjacent bore tut. The diameter of rib M. is large enough to allow ball dctcnt '72 to be received within groove Ml in pin 66; however, the diameter of rib lift. is small enough to retain ball detent 72 within bore 73 and prevent possible loss thereof. it will also be noted that a jack assembly lid mounted on the hinge detent member 593 and the panel mounted hinge member Zl lsupplies an electrical connection to the root panel when the members and lb are locked to each other shown in H6. l2. While the lefthand hinge assembly is symmetrical to the right-hand hinge assembly Elli it is not necessary for the left rand hinpc intsembly to include a jack assembly as a connection to ground is sufficient.

Referring to MG. 2., right" and left-hand latch members tin and are pivotally supported on the roof panel by rightand left-hand plates Em and E li which are conventionally attached to the roof panel The latch members ilti and till are controlled by sleeve and pin detects as will be hereinafter described. Associated with the plates 9b and W. are ripntand left-hand release brackets .M and 9d, respective whose function in controlling movement oil latch members lid and lib will be hereinafter described. The roof panel Mi also supports rightand left-hand manual release levers n and H Con- "lowden cables MM: and. connect the rclca ever Mill to the release brackets and @b, respcctiv y. ntand lefthand solenoids Illltl are mounted on plan." and "9?. by conventional mounting means and the on n thereof will be hereinafter described.

FIGS. 3, 4, and 5 show enlarged views of the left-hand latch member 88 and illustrate the function thereof. The right-hand latch member 86 functions in a similar manner but of opposite hand and will not be described.

As best seen in FIG. 3, the plate 92 includes an upstanding lug 114 which carries a pin 116. The pin 116 pivotally supports the latch member 88 for movement between a latching position as shown in FIG. 4 and an unlatching position as shown in FIG. 5. ln the latching position, the latch member 88 is engageable with a pin 118 conventionally mounted on the windshield header 24 and the roof panel 26 is thus retained in the closed position. When the latch member 88 is in the unlatching position, the roof panel 26 is free to move between open and closed positions. A torsion spring 119 carried on the pin 116 biases the latch member 88 to the unlatching position such that edge 120 of the latch member88 is engageable with a suitable stop, not shown, mounted on the plate 92. The latch member 88 includes a cutaway portion that provides a shoulder 124. In the latching position, the free end of a sleeve detent 122 engages the shoulder 124 to block movement of latch member 88 toward the unlatching position. The sleeve detent 122 is slidably mounted on the plate 92 by aligned apertures in lug 114 and in lugs 126 and 128. A spring 130 is concentrically positioned about the sleeve detent 122 between the lugs 126 and 128. One end of the spring 130 abuts lug 128 and the other end abuts a washer 132 attached to sleeve detent 122. The spring 130 biases the washer 132 into engagement with lug 126 to bias the sleeve detent 122 to a locking position as shown in FIG. 3. The release bracket 96 is attached to the other end of the sleeve detent 122. Actuation of either of the release levers 98 or 100 causes Bowden cable 104 or 108 respectively to move the release bracket 96 and the sleeve detent 122 to an unlocking position to the right of the locking position shown in H0. 3. When the sleeve detent 122 is in the unlocking position, the free end thereof is out of engagement with the shoulder 124 oflatch member 88.

A pin detent 134 is concentrically positioned within the sleeve detent 122. Upon movement of the sleeve detent 122 to the unlocking position, the latch member 88 will move slightly toward the unlatching position and shoulder 124 will then abut the pin detent 134 if the detent 134 is in the locking position shown in FIG. 3. The latch member 88 will thus still be retained substantially in the latching position and will retain the roof panel in the closed position. The solenoid 112 has an armature 136 that is attached to the pin detent 134. The sole noid 112 also has a spring 138 which biases the armature 136 and the pin detent 134 to the left to the locking position shown in FIG. 3. Actuation of the solenoid 112 moves the pin detent 134 to an unlocking position to the right of the locking position shown in F16. 3. If this movement occurs prior to or simultaneous with the movement of the sleeve detent 122 to the unlocking position, the shoulder 124 of latch member 118 will not abut pin detent 134 and the spring 119 will not exert any force on pin detent 134. The solenoid 112 will thus require very little force to move the pin detent 134. When both the sleeve detent 122 and the pin detent 134 are in their respective unlocking positions, spring 119 moves the latch member 88 to the unlatching position and the roof panel is free to move between the open and closed positions.

H05. 6 through 9 show the right-hand release lever 98 which functions to actuate cables 102 and 104 in the same manner as the left-hand release lever 100 functions to actuate cables 106 and 108 but of opposite hand. Release lever 98 includes ears 140 and 142 which have apertures receiving a support rod 144 that pivotally supports the release lever 98 in a housing 146 mounted in roof panel 26. The cars 140 and 142 also have apertures which receive a release rod 143 to which is attached Bowden cables 102 and 104. Release rod 143 extends through slots 154 in housing 146 to limit movement of the release lever 93 between an unactuated position shown in FIG. 8 and an actuated position shown in H6. 9. Springs 150 and 152 bias the release lever 98 toward the unactuated position. Movement of the release lever 98 toward the actuated position causes the release rod 148 to actuate Bowden cabies 102 and 104. Upon initial movement of the release lever 98, the release rod 148 releases a leg 156 of a normally closed microswitch 158 to allow the switch to close. Actuation of release lever has the same effect on a similar switch 160, not shown.

Referring now to FIG. 14, a source of power 162 has a first side connected to ground and a second side connected to the first side of a switch 164. Switch 164 has an open position and a closed position and is responsive to the position of a transmission selector lever so that the switch 164 is in the closed position when the transmission selector lever is in the park" position and is in the open position at all other times. The jack assembly 84 connects the second side of switch 164 to the first sides of solenoids and 112 which are in parallel. The second sides of the solenoids 110 and 112 are connected to each other and to the first sides of switches 158 and 160. The second sides of switches 158 and are connected to each other and to ground. When either release lever 93 or 100 is actuated, switch 158 or 160 will be closed to thus actuate the solenoids 110 and 112 if the transmission selector lever is in the park position.

From the foregoing, it is clear that actuation of either of the release levers will move the sleeve detents to unlocking positions but that the pin detents will remain in locking positions if the transmission selector lever is not in the park position. The pin detents will thus retain the latch members in latching position and consequently the roof panel in closed position during operation of the vehicle. lt is also clear that the hinge assemblies will cooperate with the latch members to retain the roof panel in the closed position and allow removal of the roof panel in the open position.
